I been testing new things for the past months...almost a year. I am doing good with some campaigns I did last year, but everything I am trying now seems to fail.
Maybe I am being too conservative, or maybe I am doing things wrong, but I would like to know how much you test, how many campaigns and new things you test before something succeed?
I am scared on keep testing and loose everything I gain in the past, at the same time I know that if I don't do anything new that works I will loose my previous gains anyway.
Tips, experiences will be appreciated.
